 Why do miners' power supplies have higher and higher requirements for efficiency and reliability?

Due to the long-term operation of the miners, it is very important to have a good power supply for the stable operation of the miners. It can provide the power miners require to operate and make "mining" relatively power-saving. Therefore, a good power supply quality is the prerequisite for miners' continuous and stable output. On the one hand, the stability of the miner's power supply is directly linked to the miner's life; on the other hand, it is closely related to the stability of the user's income.
Regarding "mining" costs, the highest cost for miners is not purchasing miners but electricity. Take Antminer L7 as an example; the hash rate is 9500MH/s, the power consumption is 3.425kW, and the energy consumption of L7 is 3.425kW*24=82.2 degrees in the case of 24-hour uninterrupted operation. The power consumption will be excellent when thousands of units run simultaneously. If the power efficiency of the miners can be improved, it will save a lot of money for the miners.

To maximize "mining" income, the power consumption efficiency of miners can be effectively improved from the following two aspects.
1. Increase the hash rate/power ratio of mining chips
In other words, it is to let miners consume as much electricity as possible to generate a hash rate and then dig out more bitcoins per unit of time. However, increasing the hash rate will involve many aspects, such as ASIC chip frequency and network speed. However, this also requires the help of relatively advanced foundry technology, so the cost of ASIC chips is often higher than other chips.
2. Improve the power efficiency of the miner's motherboard
The miner power supply is a system that needs to be optimized in many aspects, such as technological innovation, topology innovation, and product innovation. There are two main directions for miner power optimization: increasing power and power conversion efficiency to ensure relatively low power consumption while outputting a high hash rate. The under voltage, short circuit, overload, over temperature protection, and other technologies that come with the power supply also guarantee its stable operation.
In the process of improving the efficiency of the miner's power system, SiC (silicon carbide) is a representative technology that allows miners to continue to move towards higher power density. Therefore, it plays an important role in the miner's power system, and high-performance power devices are used as the primary method to improve the power efficiency of the miner's motherboard.
As a semiconductor material, SiC has the advantages of a high breakdown electric field, high thermal conductivity, high electron saturation rate, and strong radiation resistance. These are good ways to improve the miner's power supply and conversion efficiency.
In terms of increasing the power of the power supply, SiC is a new type of semiconductor that can withstand high voltage and high current, so it is a natural advantage for power improvement. Therefore, it can bring positive changes to the power supply of miners. At the same time, because SiC devices have lower switching and conduction loss, they can significantly reduce heat dissipation devices in the system and use innovative topologies to reduce the size of passive devices, such as capacitors, to achieve higher power density. Furthermore, siC devices have very low on-resistance to achieve higher efficiency levels in improving power conversion efficiency. In addition, compared with traditional Si devices, SiC devices perform better in terms of thermal breakdown, voltage/power surge protection, etc. As a result, siC devices can help miners improve efficiency, reliability, and thermal management.
Here, I would like to recommend several Sic devices sold by ZEUS MINING to help miners’ power supplies cope with the increasingly high power requirements and, at the same time, make “mining” more efficient and energy-saving.

The first device is the C3D06060, a 600V 6A silicon carbide Schottky rectifier commonly used in rectifier and recovery rectifier switching applications.
MSP10065V1 10A 650V SiC diode offers higher efficiency and faster recovery time than silicon diode alternatives. It can be widely used in PFC/power inverter/converter, superpower supply, etc.

B2D10065K is a SiC Schottky diode without reverse recovery current; because of its wide bandgap (3.26eV), high critical field (3*106V/cm), and high thermal conductivity (4.9W/cm·K), power Semiconductor devices are more efficient, faster, lower cost, smaller in size, and lighter in equipment.

At present, major countries and regions in the world have increasingly strict requirements on power supply quality, and power supply products with high energy consumption and low quality will be gradually eliminated. During this process, we also strive to provide you with more components for miner power supplies. You can contact sales for more product information.
